Overview
Mediapad is an open-source printed circuit board by null-ll, from the null-ll/mediapad repository on GitHub. It is a 2-layer board of 66.7 × 88.1 mm with 50 parts on 55 nets, routed with 521 tracks and 11 vias.
It is built around the ATMEGA32U4-AU and WS2812B. Its parts include 15 capacitors, 5 resistors, 4 diodes, 1 IC and 1 crystal. It belongs with the keyboards and input boards and the AVR (ATmega, ATtiny) boards of this library.
Main components

README.mdmediapad
A simple 3d printed volume/media controller macropad with 3 MX-style keyswitches and 8 customizable WS2812B RGB LEDs! Runs on QMK firmware.
Case is still a WIP. Current version requires drilling holes into the top housing for the screws. The USB cutout also seems a bit off but that could just be poor tolerances from my 3d printer.

Questions
How big is the Mediapad PCB?
It measures 66.7 × 88.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mediapad use?
50 parts, built around the ATMEGA32U4-AU and WS2812B. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mediapad KiCad files?
From the null-ll/mediapad repository on GitHub, at the commit this page was made from: the board is pcb/mediapad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mediapad design in my own project?
Its repository states no licence, so its author keeps all rights: ask null-ll before reusing the design.
